Description

technical field [0001] The invention relates to the technical field of composite material synthesis, specifically a RGO / MWCNT / HA / Fe 3 o 4 Methods of synthesis of composite materials. Background technique [0002] Carbon Nanotube (CNT for short), like diamond, graphite, and fullerene, is an allotrope of carbon. It is a tubular carbon molecule, each carbon atom on the tube takes sp 2 Hybridization, combined with carbon-carbon σ bonds to form a honeycomb structure composed of hexagons as the skeleton of carbon nanotubes. [0003] Reduced graphene oxide (Reduced Graphene Oxide, RGO for short) is graphene that has been chemically oxidized by a strong oxidant and then reduced. [0004] RGO and CNT are commonly used to synthesize RGO / CNT composites, in which RGO / CNT serves as the host of a three-dimensional scaffold with good electrical, thermal and mechanical properties. However, the composite materials synthesized in the prior art are only suitable for the fields of hydrogen...
